ADJUSTABLE STANDARD FOR- MIRROR-FRAMES, 80C.

SPECIFICATION forming part of Letters Patent No. 707,707, dated August26, 1902.

Application filed February 8,1902- Serial No. 93,146. (No model) nois,have invented certain new and useful.

Improvements in Adjustable Standards for Mirror-Frames and otherArticles, of which the following, when taken in connection with thedrawings accompanying and forminga part hereof, is a full and completedescription, suflicient to enable those skilled in the art to which itpertains to understand, make, and use the same.

The object of this invention is to obtain an adjustable standard formirror-frames and other articles by means of which the frame may beplaced in any desired position, as by swinging the bracket of thestandard on its base and also by moving the frame at the end of thebracket into any desired plane.

The manner in which I obtain the object sought by me is by constructinga bracket pivoted to its base in the ordinary way and attaching themirror-frame or other article to the outer end of such bracket byauniversal joint of peculiar construction, as herein set forth.

I have illustrated the device embodying this invention in the drawingsreferred to as accompanying this specification, andwhere- 1n Figure l isa side elevation of a bracket, the base of such bracket, a frame, and auniversal joint by means of which the frame is attached to the bracket.Fig. 2 is a side elevation of the bracketillustrated in Fig. 1, suchbracket being turned in its base, so that such base is shown in frontelevation, a rear elevation of the frame illustrated in Fig. 1, and acombined side and rear elevation of the universal joint of the device.Fig. 3is a side elevation of the ends of the bracket to which theuniversal j ointis attached and of a short section of one of the shaftsof the universal joint. Fig. 4. is a horizontal sectional view of theend of the bracket which is illustrated in Fig. 3 on line 4 4 of suchFig. 3. Fig. 5 is a perspective view of a U-shaped sheetmetal piece(preferably made of spring metal) forming an element in the universaljoint by means forming the connection between the bracket and the framesupported thereby.

Fig. 6 is a top plan view of the base of the universal joint, such basebeing attached to the backing of the frame and preferably made of springmetal; and Fig. 7is aside elevation of the base illustrated in Fig. 6.

A reference-letter applied to designate a certain part is used toindicate such part throughout the several figures of the drawingsWherever the same appears.

A is a bracket pivoted at one end thereof, as by pins or bolts a a, tobase B. Base B may be attached to a wall or other thing, as by screws bb.

C is a frame, and C is the backing of such frame.

D is a base, preferably made of spring sheet metal.

E is a shaft having flattened ends. Base D and shaft E are attached tothe backing C of frame C, as by the bolts e (2, having nuts 6 c thereon.

(Z d are friction springs coming in contact with the curved portion ofU-shaped piece F. The springs 01 d are preferably integral with base Dand are formed or punched up from such base in the mannershown in Figs.6 and 7. The U-shaped piece F extends around the body of the shaft E andis attached to the free end of bracket A by rivet or bolt f. WVhen thepart F is constructed of spring sheet metal, the bolt or rivetf is drawnor set sufficiently tight to obtain sufiicient friction between suchU-shaped piece F and the end of the bracket A, so that the frame C whenadjusted to any plane by the turning of the U-shaped piece F on itspivot will be sufficiently stable to remain in its adjusted posi tion.When the U -shaped piece F is not made of spring metal, the springs G Gare placed into the recesses H H on the bracket A, between such bracketand the U-shaped piece F. I

To provide for wear of bolt, pin, or rivetf and also of the body of theshaft E and at the same time to obtain sufiicient friction between thebase D, shaft E, and the U-shaped piece F, the end a of the bracket A(see Fig. 3) is made concentric with the hole f in such bracket,(through which hole the bolt or rivet f extends,) with the radius ofsuch part a. sufficiently long, so that the shaft E is in c0ntact withthe periphery thereof.

To limit the movement of the shaft E and frame 0 around the bolt orrivet f, the end of the bracket A adjacent to the circular part a is cutaway on substantially the lines a a The operation of this apparatus is:When bracket A has been adjusted on its base 13 to any desired position,the frame 0 is turned into any desired plane by the movement of theU-shaped part F on its pivot f and the turning or rocking of shaft E inthe U-shaped part F. The friction between the several parts D E F issufficient to hold the mirror in its adjusted position.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a frame, a backing, such backing secured in theframe, a bracket, such bracket provided with a hole adjacent to one endthereof and provided with a circular end concentric with the hole, aU-shaped piece, a pivot, such U-shaped piece provided with a hole nearthe bend therein and attached to the bracket by extending the pivotthrough the holes in the U-shaped piece and in the bracket, a shaft,such shaft flattened at its ends and arranged relative to the U- shapedpiece and bracket to be interposed between the bend of the U-shapedpiece and the circular end of the bracket, a base, such base providedwith friction-springs stamped out of and forced up therefrom, and suchbase interposed between the shaft and the backing of the frame, andmeans to attach the base and the flattened ends of the shaft to thebacking: substantially as described.

2. The combination of a frame, a backing, such backing secured in theframe, a bracket, such bracket provided with a hole adjacent to one endthereof and with recesses in its sides near the hole, and provided witha circularend concentric with the hole, a U-shaped piece, a pivot, suchU shaped piece provided with a hole near the bend therein and attachedto the bracket by extending thepivot through the holes in the U-shapedpiece and in the bracket, springs interposed between the bracket and theU-shaped piece and held in the recesses in the bracket by the U -shapedpiece, a shaft, such shaft flattened at its ends and arranged relativeto the U-shaped piece and the bracket to be interposed between the bendof the U-shaped piece and the circular end of the bracket, a base, suchbase provided with friction-springs stamped out of and forced uptherefrom, and such base interposed between the shaft and the backing,and means to attach the base and the fiattened ends of the shaft to thebacking; substantially as described.
